Eaton SPC050120N5P Surge Protection Device - UL 1449
Part Number: SPC050120N5P
Quick Summary
Eaton SPC050120N5P surge protection device is a 50 kA SPD designed to shield 120 V, single-phase power systems in industrial and commercial panels. Power surges from switching, lightning, or grid disturbances can cause unplanned downtime and equipment damage; this SPD helps prevent that. UL 1449 certified, housed in a NEMA 4X enclosure, and backed by a 10-year warranty provide reliability and compliance. Its alarm and Form C relay offer immediate fault signaling, while external side mounting simplifies retrofit in existing panels. Designed for panel builders, integrators, and OEMs, the SPC050120N5P supports efficient installation, predictable maintenance, and long-term total cost of ownership improvements.

The SPC050120N5P delivers a robust 50 kA surge capacity, directly translating to improved load protection. The business impact is lower risk of downstream equipment damage and fewer production interruptions, even in environments with frequent transient events. In practical terms, panel builders can design more resilient systems for drives, PLCs, and control electronics, reducing unplanned downtime and costly warranty claims. With a 120 V rating and single-phase configuration, this device aligns with standard industrial control circuits, minimizing wiring complexity and compatibility issues. The result is faster installations, fewer field adaptation components, and better installation quality—critical for commissioning windows and changeovers in manufacturing lines. The NEMA 4X enclosure provides moisture, dust, and corrosion protection for panel-mounted protection in wash-down or outdoor environments. This makes it suitable for outdoor panels, process skids, and electrical rooms where environmental exposure is a concern. Alarm and Form C relay provide discrete fault signaling and wiring options to BMS or PLC systems, enabling immediate maintenance triggers and easier root-cause analysis. External side mounting simplifies retrofits by leaving existing panel enclosures accessible for installation, reducing downtime during upgrades. A 10-year warranty and UL 1449 certification further support ongoing performance, regulatory compliance, and total-cost-of-ownership advantages for OEMs and service providers.

FAQs
Consider external side mounting to simplify retrofits and ensure adequate space for wiring to the Alarm and Form C relay. Confirm 120 V single-phase input matches the panel's distribution circuitry, and provide proper clearance for venting and maintenance. Use appropriate grounding and follow manufacturer mounting guidelines to maximize protection and minimize installation time.
Key specs include a 50 kA surge rating, 120 V operating voltage, single-phase configuration, NEMA 4X enclosure, UL 1449 certification, and integrated Alarm with Form C relay. It weighs approximately 2.5 lb and is designed for external side mounting in industrial panels, delivering reliable transient protection with a 10-year warranty.
Yes. The NEMA 4X enclosure provides moisture, dust, and corrosion resistance, making it suitable for wash-down zones, outdoor panels, and damp or dusty environments. It supports reliable protection for PLCs, drives, and control electronics where environmental exposure could otherwise compromise performance and uptime.
The SPC050120N5P is UL 1449 certified, indicating compliance with essential safety and performance standards for surge protection devices. The NEMA 4X enclosure further supports protection against moisture and contaminants. Together, these credentials help with regulatory acceptance, industry best practices, and reduced risk in certified electrical installations.
By limiting transient damage to critical loads, it reduces unplanned downtime and component replacement costs. The built-in Alarm and Form C relay enable rapid fault notification and easier maintenance scheduling, while the 10-year warranty lowers lifecycle risk. Its external side mounting also speeds upgrades, minimizes panel downtime, and supports scalable protection across multiple lines.
